TRIUMPH SPRINT 955 [1999-2004] - Z-ring chain

The Regina 525 HPE Z-Ring Chain with Rivet Link sets new standards in motorcycle chain performance and durability. This innovative chain eliminates the need for regular relubrication that motorcyclists typically have to do every 1,000 km. Extensive laboratory and road testing has proven that the HPE chain has a lifespan at least equal to, if not longer than, traditional regularly lubricated Z-ring chains.

A standout feature of the Regina 525 HPE chain is the tetrahedral amorphous carbon (ta-C) coating, one of the most advanced forms of DLC (Diamond Like Carbon) coatings. This coating is applied to the surface of the bushings and rollers and reduces energy losses while increasing efficiency in the secondary drive. The extremely high hardness of the coated surface combined with a low coefficient of friction results in improved performance.

The Regina 525 HPE chain also minimizes environmental impact by eliminating chain cleaning and lubricant splash during operation. This technological innovation was developed through intensive research and development work by Regina engineers in Italy. The chain is ideal for motorcyclists who value performance, durability and environmental friendliness.
